Limia, a citizcirof the-United States7 reaiding in the city ot' St. Louis,y in the State have invented a certain new and useful Sewing-liiachinc,of which the following is such a tali, cicai'. andexact description as will en@ able any. onolsk'illed in the art to which it appertains "to make and uae. the Same, reiference heiiigjhad to the accoiniiianying drawings, forming part othis Speciiicatirm.

lli/ij; invention vrela-tes to sewing machines, and more particularly/to blind stitch sewing machines, though seine-of the it iatures of my inreiitioi?A are Iapplicaclcto .other types ot .sewinginagliines. l

The general construction and ,operation of un7 machina iig-similar to that showirand described in"l"atent 862.5330, issued to inc Yiruguiit (L iflii, and many ofthe features Shown in the present aiipiication are `not clah'ncd in this applicatioigi because. the' same are described and `clainicd in my said priorpatexit,

(ue it the principal objet-,t5 of ,my m

ren'tion is to provideimproved means torv insuring the proper cooperation ot the neodl i, and thc beak ot the looper in the 'dittfci'ent .lateral positions; ot the needle and in uniform relation to the time ot the take-up7 Another object of my invention is to pro- .Avide improved means for operating and adjustii'ig' the haci( guides.

Fitill another object ot' my iniciition is to proridy an improrcd 'torni of needle guide.
